![]() We will then modulate the data signal with a with a carrier signal, use a photo diode to receive the optical signal and then send it through a low pass filter to extract the data signal. we will be combining a noise source with our data signal to how noise will affect it. In this example we have a user defined bit sequence connected to an NRZ pulse generator which will represent the data signal. The noise source block acts as a source of thermal noise. We will then observe the effects of changing the noise properties.
